Hi Please check if my answers are correct! :)

Question 1 1 pts Use the following diagram to answer the next question. A motorboat travelling at a constant velocity pulls two water-skiers behind it. Each rope makes an angle of 25.0 with respect to the back of the boat. If the boat exerts a force of 700 N, the tension in each rope is N. (Record your answer as a three-digit number.) 760 Question 2 1 pts A small boy pulls his 20 kg wagon, accelerating it at 1.5 [11/52. There is a force of friction of 5.0 N opposing him, and the handle of the wagon makes an angle of 45 to the ground. The force the boy exerts along the handle is N. (Record your answer as a two-digit number.) Question 3 1 pts While running an obstacle course, Jane comes to a rope hanging from a platform. She grabs a rope, which then accelerates her up into the air. Her mass is 55.0 kg, and she accelerates upward at 1.50 mfsz. The tension in the rope is _ N. (Record your answer to three signicant digits.) 82.5 Question 4 1 pts A 2,900 kg car starts down a vertical mine shaft with an acceleration of 1.50 mlsZ. Determine the tension during the start of the motion. Put your answer in scientic notation a.bc x10d and put abcd in the numerical response below. Question 5 1 pts A 725 N student stands on a bathroom scale while riding in an elevator. The student observes that the scale reads 775 N as the elevator begins to rise. Find the acceleration of the elevator as it begins to rise. Place your answer below to 2 sig gs Question 6 1 pts A 275 N box is sliding down a 35.0 degree incline. If the force of friction along the incline is 96.0 N, what is the acceleration of the box? 2.2 Question 7 1 pts You are travelling in your car at a velocity of 24.0 m/s east when you slam on your brakes. The force of friction on your car tires is 1.80 x104 N. If the mass of you and your car is 1.50 x 103 kg, how far do you skid before coming to a stop? A. 24.0 m B. 0.65 m C. 165 m D. 20.4 m Question 8 1 pts What is the mass of a 4.00 kg bowling ball? A. 392 kg B. 392 N c. 4.00 N D. 4.00 kg Question 9 1 pts You just got a couple of identical 20.0 kg shopping carts to do some shopping. The reason you have two is that they are unfortunately stuck together (and it was the last one available and you need to stock up on toilet paper). You push them into the store to get help pulling them apart. You are running towards the store accelerating the shopping carts at 1.2 mlsZ. Determine the force the second cart exerts on the rst cart. Illustration 1 .' Two shopping carts being pushed. Please IGNORE the sign of the answer, I just want the magnitude. 24
